When I began riding I sought out a trainer and since I live in a remote town we have 1 dressage, 1 English and 1 natural horsemanship trainer, I wanted to focus on behavioral training and the later had great recommendations. So I began training with her and she turned my horse around. I was 16 and had never had training and my horse was back yard bred plus had not been worked with in over 2 years. I always rode western and my trainer focused alot on teaching me to understand how the horses brain works so I could be better prepared to learn how to assess the situations that I was sometimes in. I never learned how to ride properly and Im sill correcting my seat and so forth but I have excellent communication with my horse and I wouldn't trade that for the world. It taught me that with patience I can get my horse to do anything... I've had 4 horses ranging from 2yrs old to 16 years old and all of them will do anything asked because 1. They TRUST me and 2. I know how to redirect their mind into a positive mind set.
*by anything I mean, lakes, ocean waves, crossing deep rivers, cars, parades, rodeos, horseshows, new trails, they all have been great with other horses not aggressive, 2 year old children, and these are horses I got for free or close to free.
People always comment on how well trained my horses are and it all comes from their mind set and mine.
The only thing I learned from Parrelli is left and right brain introvert and extrovert. And I love double notted halters :)
I basically comes down to this:
UNLESS you are beating and scaring your horse into submission which usually will get you no where, you are working with your horses mind and that's natural enough for me.
So forget the stereo types Clinton Anderson, parrelli, WHATEVER pick a trainer who YOU like and YOU like the results. Its YOUR horse.
HAPPY TRAILS :)
